INVINH1 Gene Alleliс Polymorphism in Maize Accessions from VIR Collection

Аннотация

The sequences of the apoplastic invertase inhibitor gene INVINH1 were identified in 71 maize accessions from the collection of the Vavilov All-Russian Institute of Plant Genetic Resources (VIR). In total, 35 INVINH1 allelic variants were found. In 21 maize accessions, at position –95 from the start codon, INVINH1 contained an extended insertion (143, 190, 192, or 210 bp). In INVINH1 proteins, 21 amino acid substitutions were identified, six of which (A49V, A49G, A65P, S97I, C99R, and D108Y), predicted to be radical, were localized in the PMEI functional domain.
